VuXML IDDescription
012809ce-83f3-11ea-92ab-00163e433440OpenSSL remote denial of service vulnerability

Problem Description:

Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognized signature algorithm is received from the peer.

Impact:

A malicious peer could exploit the NULL pointer dereference crash, causing a denial of service attack.

1d56cfc5-3970-11eb-929d-d4c9ef517024OpenSSL -- NULL pointer de-reference

The OpenSSL project reports:

EDIPARTYNAME NULL pointer de-reference (High)

The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack.
